HOOF-SPREADING' HORSESHOE.

SPECIFICATION forming part of Letters Patent No. 579,303, dated March 23, 1897.

Application filed July 31, 1896. $erial No. 601,141. (No model.)

To all whom, it may concern.-

Be it known that I, ALEXANDER PEARSALL, a citizen of the United States, and a resident of Locust Valley, county of Queens, and State of New York, have invented certain new and useful Improvements in Horseshoes, of which the following is a specification, reference be ing had to the accompanying drawings, forming a part thereof, in which similar letters of reference indicate corresponding parts.

This invention relates to an improvement in horseshoes, the object thereof being to supply an article of this character adapted for automatically spreading the heel of ahorses hoof and preventing the same from contracting.

The device comprises few and sim ple parts, and it is durable and inexpensive, it does not weigh any more than an ordinary horseshoe, and it is adaptable for attachment to the horses hoof by the ordinary process of nailing.

The invention will be hereinafter fully described, and specifically set forth in the annexed claim.

In the accompanying drawin gs,forniin g part of this specification, Figure 1 is an inverted plan view of my improved horseshoe, showing the same in the position that it will assume when it is attached to a horses hoof; and Fig. 2 is a similar view showing the normal position of the shoe before it is attached to the 1100f.

In the practice of my invention Iprovide a shoe comprising three sections A, B, and 0. Of these three sections the section A comprises a front or toe portion of the shoe, and it is of a segmental contour in plan. The

two other sections B and O comprise the heel portions of the shoe, and they are hinged to the section A by means of pivots E,which said pivots are preferably riveted, whereby the parts are securely maintained in connection with each other, while at the same time the sections B and O are adapted for swinging motion, as illustrated in Fig. 2 of the draw ings.

The section A of the shoe is provided with a cross-braee A, which said brace preferably forms an integral part of the said forward portion A of the shoe. Attached to this said brace by a screw, rivet, or other suitable means a is a plate-spring F of a normal semi.- elliptical contour. The two ends of this said and c of the swinging arms or sections B and 0, comprising the heel portions of the shoe.

In the operation and use of the device the toe portion A of the shoe will first be nailed to the horses hoof. be pressed toward each other and also nailed to the 1100f, and inasmuch as the act of pressing the two portions together compresses the spring F the tendency thereof will be to force spring engage, respectively, with recesses l) The side portions will then the sections 13 and O of the shoe apart, wherethe side portions having recesses therein for engagement with the ends of a semielliptical spring, which spring is attached to the brace of the said front portion of the shoe, sub-- stantially as shown and described.

In testimony that I claim the foregoing as my invention I have signed my name, in presence of two witnesses, this 29th day of July,

ALEXANDER PEARSALL.
